What is GPT4 Turbo API?
GPT4 Turbo API is a service that allows developers to access and use the GPT-4 Turbo model, which is the latest and most powerful language model developed by OpenAI. GPT-4 Turbo can generate realistic and coherent text for various purposes, such as chatbots, content creation, code generation, and more.
It can also accept image inputs and output text in the future. GPT-4 Turbo has a context window of 128,000 tokens, which means it can take in the equivalent of 300 pages of text at once. This enables it to have broader general knowledge and advanced reasoning capabilities. GPT-4 Turbo also comes with improved instruction following, JSON mode, more reproducible outputs, and parallel function calling.
How can I Get Access to GPT-4 Turbo API?
Access to the model is available to anyone with an OpenAI API account. You can utilize the model by specifying “gpt-4-1106-preview” as the model’s name in the API.
How to Create an Account to Get your GPT-4 Turbo API Key?
To create an account and get your GPT4 Turbo API key, you need to follow these steps:
- Go to the API signup page and create your account. You will need to provide your email address and your phone number.

- Go to the API keys page and create a new secret key.
- You will need to have a debit or credit card and add at least $5 of prepay credit to your API account.

- Use the secret key to access the GPT-4 Turbo models via the OpenAI API.

- You can use the Chat Completions API to interact with the models using natural language instructions.
Make Your First Request to GPT4 Turbo API
Here’s a straightforward breakdown of the process into four clear steps:
- Retrieve your API key: Ensure you have already generated this key, typically represented as a lengthy combination of random numbers and letters. Keep it securely stored.
- Launch your terminal: To begin experimenting with curl, open your terminal.
- Enter the curl command: Curl is a command-line utility used for data transfer. For the chat API, you can use a command like this:
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
https://api.openai.com/v1/chat/completions -d \
'{
"model": "gpt-4-1106-preview",
"messages": [
{
"role": "system",
"content": "You are an assistant."
},
{
"role": "user",
"content": "Hello!"
}
]
}'
- Replace “YOUR_API_KEY” with your actual API key. The string following “-d” specifies the request body in JSON format. It defines the model as “gpt-4-1106-preview” (GPT-4 Turbo) and includes two messages: a system message that sets the assistant’s role and a user message.
- Execute the command: After hitting “Enter,” you should receive a response from the API in your terminal window within a few seconds, at most.
Keep in mind that this is a basic example, and you may want to customize the request to suit your specific requirements, such as adding more messages to the conversation.
Enable the JSON Mode with GPT4 Turbo API
“Enabling Consistent JSON Output with GPT-4 Turbo and GPT-3.5 Turbo Using the New JSON Mode”
(For the introduction, it may be useful to mention that JSON is a data format for both human and computer readability, organizing information in a “name: value” pair structure.)
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
https://api.openai.com/v1/chat/completions -d \
'{
"model": "gpt-4-1106-preview",
"messages": [
{
"role": "system",
- "content": "You are an assistant."
+ "content": "You are an assistant, and you only reply with JSON."
},
{
"role": "user",
"content": "Hello!"
}
- ]
+ ],
+ "response_format": {
+ "type": "json_object"
+ }
}'
- It’s evident that we’ve included a new component:
"response_format": {
"type": "json_object"
}
- We’ve configured the system message to read “You are an assistant, and your responses should strictly adhere to JSON format.” However, it can be customized to suit your preferences, as long as it references “JSON.” It’s essential to maintain this reference, as the absence of “JSON” in the system message will result in an API error, specifically: “‘messages’ must include some form of ‘json’ to utilize the ‘responseformat’ of ‘jsonobject.'”
{
"role": "system",
"content": "You are an assistant, and you only reply with JSON."
}
- Please exercise caution, though. While the model will consistently generate JSON-formatted responses, achieving 100% accuracy in their structure may remain challenging.
